Can anyone direct me to the location of the relevant ISO standards for the tolerances applied to metric screw threads that are to be coated. Coating thickness can range from 15-31 microns per coated surface. We have two situations:-
1. Coating is applied to the screw only.
2. Coating is to be...
Thanks, Desertfox & BigInch.
Every bit of information that comes through makes the muddy water clearer. The problem that I am trying to solve is transverse to the pipes longitudinal axis. However the X setion of the object for which I am trying to solve is more like a c section. A pipe with...
BigInch, Cockroach and Stanier, thanks for you tips. BigInch the formulae I found was:-
Pipe bending stiffness = EI/(0.139r^3)
Where:-
E = pipe material modulus of elasticity
I = pipe wall moment of inertia per unit length.
I found this in reference material for thermoplastic piping. Nowhere in...
Could anyone inform me how to calculate the pipe bending stiffness and pipe hoop stiffness for metallic pipes. I have found formula's for the above but the reference material I have suggests that these formula's are for non-metallic pipes. Please help.
Thanks for your response mog69, I did try the manufacturer of the rubber section and I spoke to their technical department and then their consultant. It was the consultant that confirmed the rubber section would transmit a force but could not give me any info on how much. Do you know where I...
Dear all, could anybody give me a clue on how to calculate what percentage of force is transmitted through a rubber section as a result of compression?
Please help, I have spoken to many people who could not shed any light on this apart from it will transmitt a force.
Is it possible to derive the pressure of air flowing through a pipeline from the volume flow rate and the diameter of the pipe. For instance pipe I.D. = 150mm and volume flow rate = 0.3m³/sec.
I have looked at Bernoulli's eqn and the continuity eqn and hence come to the conclusion that the...
